REMOVING IMPURITIES FROM STEAM-BOILERS.

SPECIFICATION forming part of Letters Patent No. 382,508, dated May 8.1888.

Application filed November 19, 1887. Serial No. 255.671. (No model.)

Apparatus for Removing Impurities from Steam -Boilers, which I desire toprotect by Letters Patent of the United States, of which the followingis a specification.

The object of my invention is to remove the impurities of the waterinthe boiler before in- The tendency of impurities in boilers is toaccumulate upon or near the surface of the water during ebullition orunder the boiling operation. This tendency is taken advantage of in myimprove ment, and the sedimentary-matter is removed while in suchcondition.

In the accompanying drawing, making a part of this specification, afurnace and boiler are shown, the walls of thelatter being broken awayto show the interior thereof.

The boiler, of usual construction, is designated A. Tubes b, also ofordinary construction and application, are'shown in said boiler.

As a principal feature of my invention, I locate within andlongitudinally of the boiler one or more perforated tubes, at. This tubeI preferably make equal or nearly equal to the length of the boiler, andsupport it by securing its ends to the boiler-stays, or in any mannermost convenient. Tube a is so located in the boiler as to be somewhatbeneath the sur- By' the application of a sleeve or coupling, 0, tubeais connected with a pipe, d, extending through the top of the boiler, bywhich tubea may be partly or wholly supported. An extension of pipe (1,or connections of pipes, therewith, is brought from above the boiler toa position below, and is connected with a deposit-chamber, B. Oonnectedwith chamber B, and extending above a the boiler, thence through the topof the boiler, and-terminating near the bottom on the interior of saidboiler, is a-pipe, e. The chamber -B at its-upper end consists of twocurved branches,-D and D, to which the connections, respectively, withtubes d and e are made. Centrally and longitudinally of chamber B isinserted a tube, j, perforated, as permitted to appear through thebroken wall of said cham her. A continuation of tube j is shown in pipe5, terminating downwardly. Pipe d is supplied with a cock, 8, pipee witha cock, t, and

piped with a cook, it. The first two are normally open.

The operation of discharging the sedimentary matter from the boiler hasits first stage in the tendency of such matter, through agitation orpressure, to enter the tube a through the perforations thereof. It isthen forced through piped to chamber B. At this point the curved form ofthe entrance-branch D tends to direct the water, withits freight offoreign matter,

to the bottom of chamber B, and, being acted upon by gravity andretarded within the cham her, the foreign matter is deposited, and thewater thus'relieve'd passes out through pipe ,e and into the boilerbelow the sediment.

Tube j and piper are for the purpose of cleaning out chamber B, whichmay be done by closing cock t of pipe 0 and opening cook a of pipe i,when the water from the boiler through pipe 01 is forced to find exitthrough said cleaningtube and pipe, thus blowing out the chamber B. Torelieve the chamber of any incrustation not acted upon by the Vblowing-out process, a hand-hole, E, is provided in the side of thechamber, to give access to the latter and permit removal of suchdeposit. p

- I am aware that it is not new to carry off the accumulation of foreignmatter by appliances in some respects similar to mine, and I thereforedo not broadly claim every device that may be used for collectingthe. matter at or near the water-surfacein the boiler, nor broadly claima deposit-chamber interposed between pipes leading from and returning tothe boiler.

Having thus described myinvention, what I 0 claim, and desire to protectby Letters Patent, 1S5
